Java讀取char數據: System.in.read()

 

public class getchar
{
    public static void main(String[] args)
    throws java.io.IOException //必不可少
    {
        int num = System.in.read(); //讀進來的數，默認保存為整數，如果需要輸出 剛才輸入字符，需要用char進行強制轉換(type cast)
        char c = (char) num;
        System.out.println("the char you've just input is: " + c + "\nits unicode number is: " + num);
    }
}
